Sohal tang got schooled

[Coleus]

So couples month ago i had a sohal tang that terrorize the whole tank so i let him go. This time tried a smaller one. Got him home today, over fed all my fishes while acclimating him. Moved some rocks and put him in. He is 3 inch and all my other fishes are 3-5 inches. All my angels and tangs went after him. It looked very close to a frenzy feeding. In the past, I never see this much aggression from all my tangs and angels. Usually one or two went after new comer not the whole pack.

So I turned off my light and the sohal is safe for now. Will continue to monitor this aggression but what the hell?
